Toa l'l whom it mag iconcem:

Be it known that I, MATHIAS A. I-Iot'rz- BAUER, a citizen'of the United States, residing at Belrnond, in th'ecounty of lWright and State of Iowa, have invented Pnew and Clutch-Pedal Mechanism for Automobiles, of-which the follow ing-is a specification. v v

The object of said invention is the provision of a simple, durable and reliable mechanism through the mediumr'of which an automobile, more particularly a Ford automobile can be changed fromneutral to low speed and 7 again changed from low speed to neutral or high speed through the medium of the clutch pedal, thereby eliminating entirely a high speed lever for operating the gears of the automobile.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure 1 is a view showing my improvement in neutral position as associated with the clutch pedal of a Ford automobile.

Figure 2 is a view similar to Figure 1 but showing the parts in low speed position.

Figure 3 is a similar view showing the parts in high speed position. V

Figure 4 is an enlarged detail view with the thrust bar held against rearward movement by the bracket.

Figure 5 is an enlarged detail view with the thrust bar in'the, same position as in Figure 2. I

Figure 6 is an enlarged perspective of the' apertured bracket of my improvement.

Figure 7 is an enlarged perspective of the dog comprised in the improvement.

Similar numerals designate corresponding parts in all of the views ofthedrawings.

In accordance with my invention I employ a clutch pedal 1 which may be and preferably is the ordinary clutch pedal, though it is not necessary for the same to have any connection with the high speedlever before alluded to. Also in accordance with my invention I employ in fixed relation to a frame 2 of the machine a bracket 3 that is arranged in front. of the clutch pedal 1 and is apertured as indicated by 4.

Extendingthrough the aperture 4 of the bracket 3 which is designed to serve as a keeper is a thrust or latch bar 5 between the forward'end portion of which and the lower end o-f the bracket or keeper 3 is. interposed. a retractile spring 6. In virtue' of the ar rang'ement shown in Figuresgl, 2 and 3 it will be-observed that the said spring 6 tends to draw the bar 5 downwardly and also tends to move the said bar 5" rearwardly. The bar.

-5'is connected at 7 preferably in adjustable v manner-to .a bar 8'that extends through and is adapted to play; in the opening '9 of .the

7 foot board 10, and is pivotally connected at 1 1'1 to'theupper-portion of the clutch pedal 1. In its lower edge and at an intermediate trainee f HQEF-ii lpoint of its length the thrust bar '5 is provided with a notch 12, the rear wall 13 of which is inclined considerably from thever- V tical as best shown in Figure 5. ,On the thrust bar 5 adjacent to the notch 12 is a lateral pin 14, and pivotally connected at 15 to the thrust bar 5 is agravitational dog16 shaped and relatively arranged as illustrated. I

In Figure 1 the clutch pedal 1 is shown in neutral position, and by reference to Figures 1 and 4 it will be observed that with the pedal 1 in said position, the pedal can bechanged to the low gear position as'shown in Figure 2 and can be-changed back to the neutral positionof Figure 1 or can be changed to high speed position, Figure3, by simply actuating the clutch pedal 1. .This will be better understood when it is stated that with the thrust bar 5 positioned as in Figure 4, forward movement ofthe thrust bar 5 will be attended by upward movement of said thrust bar 5to disengage the forward wall of the notch 12 from the keeper 4,'where-j 7 upon the tendency of the spring 6 to con-- tract will snap the thrust bar 5 and the.

clutch pedal rearwardly to the position as shown in Figure '3. 7 Again with the parts positioned as shown in Figure '1 forward 1 movement of the clutch pedal 1 will be attended by free forward movement of the thrust bar 5 into the position shown in Figposition shown in Figure 3. r The rearward movement of the thrust bar 5 and the dog 16 being attended by the riding of the lower edge of the dog 16 over the lowenwall of will move the clutch pedal rearwardly to the,

theaperture 4 in the keeper or bracketplate J 3. V In this connection it will beunderstood ure 2. .When the parts are positioned as 1 at present in use.

that the pin 14 has for its'function'to, limit V V the downward and forward movement of the dog 16 so that the said dog cannot gravitate below the position shown in Figure 5.

Notwithstanding the practical advantages ascribed to my improvement it Willbe ap;

parent that the improvement is simple and inexpensive in constructionand is susceptij ble of being readily applied to automobiles, more particularly Ford automobiles, such as I have entered into adetailed description of the construction and relative arrangement of the parts embraced in the present and'preferred embodiment of my invention in order to impart a full, clear and exact understandmg of the said embodiment. I do notdesire,

however, to be understood as confining my self'to the specific construction and relative arrangement of parts inasmuch as in the a future practlce of the 1nvent1on var ous changes and modifications-may be made such as fall withimthe scope ofmy' inventionas defined in my appended "claim.
